Changing the patient when booking appointments via the calendar

I have been asked to pass some feedback regarding booking appointments via the diary.

When we book an appointment from the diary and click on the diary whilst viewing the calendar, it comes up with that appointment details box for us to start typing the patients name as normal, and now whenever a patient is chosen, it wont let you edit or change the patient, its stuck with that patient and we have to cancel and then click in the diary again to make a new appointment.

We used to be able to click back on the name and change it, now we have to cancel it and click in the diary again. Is this because of a new update to dentally? Is this something others prefer?
